Another vintage film that I brought along on our most recent visit to the ranch was a roll of Kodak 2475 Recording Film, an extremely grainy high-speed film that was once a favorite of private detectives and cops working surveillance. This relic had been in the family film closet since my earliest days of photography; the expiration date was JAN 1977. By all rights, this roll should have become completely fogged over and useless many years ago. I was pleasantly surprised when the 36 frames came out quite nicely.
